For those lucky ones that have screwed their hard drives and recovered gigabytes of randomly named photos with PhotoRec. This script takes input folder and output folder and moves all files that have EXIF tag File Source with value Digital Camera. This serves as first step on a long journey of walking through and watching all the recovered image…

	#!/bin/bash

	if [ ! -d $1 ]; then
	echo $1 " must be directory"
	exit
	fi
	if [ ! -d $2 ]; then
	echo $2 " must be directory"
	exit
	fi
